Hiltjo Posthuma wrote xscreenshot[0] which basically generates an if on stdout. The imagefile[1] tools can be used to convert the if to png using if2png (thanks FRIGN!).
This is a very useful tool, and imagefile looks like a great format. Thanks very much to everyone involved. I have a question about scripting xscreenshot and other applications that operate on X window ids: Is there a reliable way to get the X id of a window in a shell script? This seems basic, but I could not find a way to do this that works for all windows. Digging around in the output of `xprop -root` as in [0] looks far too ugly, to me, to be the right thing.
